STOVE.

Specification of Letters Patent.

Patented Dec. 26, 1905.

Application filed June 24, 1904;. Serial No. 214.004.

To all whmn it may concern:

Be it known that I, FRANK HAMMOND, a citizen of the United States, residing in the city of Jackson, in the county of Jackson and State of Michigan, have invented certain new and useful Improvements in Stoves, of which the following is a specification.

My invention relates to heating-stoves, one object residing in the arrangement and construction whereby the products of combustion take a circuitous course, thereby providing for the efificient combustion of fuel and effectually utilizing the heat derived therefrom.

Another object of the invention resides in the construction and arrangement of the stove wherein the fire chamber or pot is surrounded by a semi-annular air-distributing chamber having direct communication with the exterior of the stove-casing.

Another object of the invention resides in the formation of air chambers, ducts, flues, or passage-ways for conducting the air into and around the fire pot or chamber, thereby giv ing an extended amount of radiating-surface to the heated air in its passage through the stove to the smoke-flue.

It is still further contemplated to provide for the proper consumption and combustion of the fuel through the medium of direct and indirect air-currents.

With these and other objects in view the present invention consists-in the combination and arrangements of parts, as will be hereinafter more fully described, shown in the accompanying drawings, and more particularly pointed out in the appended claims, it being understood that changes in the form, proportion, size, and minor details may be made within the scope of the claims without departing from the spirit or sacrificing any of the advantages of the present invention.

In the drawings, Figure 1 is a vertical sectional view of the stove embodying my improvements. Fig. 2 is a vertical sectional view on the line co (0 of Fig. 1 looking from the front toward the rear of the stove. 3 is a vertical sectional view on the line I) b of Fig. 1. Fig. 4: is a horizontal sectional View on the line 0 c of Fig. 1, and Fig. 5 is a horizontal sectional view through the base of the stove on the line d d of Fig. 1.

Referring now more particularly to the accompanying drawings, the reference character 1 designates the usual casing of the stove,

formed, as usual, of sheet metalor any other suitable material. Arranged within the body of the stove is the fire-pot 2, whose walls converge downwardly, terminating in suitable shoulders for the reception and support of the grate 3, the reference character 4 designating the ash chamber or pit having the usual draftregulator door 5. Formed centrally in the bottom of the stove-casing is an opening 6, leading into the air-chamber 7, having com munication with the elongated air-chamber or passage-way 8, which latter terminates in a semi-annular air-distributing chamber 9, arranged with relation to the upper part of the fuel-chamber 2, the air-distributing chamber 9 being provided with a number of perforations 10, permitting the atmospheric air, which has become more or less superheated in its passage to the air-distributing chamber, to enter the fuel-chamber and aid in the combustion of the fuel contained within the latter. When the draft-regulator door 5 is closed or otherwise manipulated to shut off the direct draft, the atmospheric air passing upwardly through the chamber 8,th rough the air-distributing chamber 9 and into the ash chamber or pit 4c, and through the openings 10 is strongly drawn downwardly into and among the evolving gases and the smoke from the burning fuel below in such manner as to cause and continue the combustion of said gases or smoke so arising above the said fuel.

The products of combustion arising from the fire chamber or pot 2 obviously rise upwardly into the reverting chamber or dome 11 of the stove, finding exit through the flue 12, having the downwardly-directed extension 12, the extension 12 being formed and arranged in the rear of the elongated air-chamber 8 with its rear wall 12 inclined forwardly and extending toward one side only of the casing of the stove, whereby the products of combustion are conducted downwardly in the rear of the said chamber 8 and caused to circulate around the last-mentioned chamber in the chamber 13, finding way into the flue 14, whose rear wall 15 is arranged substantially parallel with the inclination of the wall 12,

From the foregoing it will be understood that air may pass through draft-door 5 into the ash-pit 4 and through the fuel-chamber 2 and from thence downwardly through the flue 12 12 and upwardly through the flue 14 to the chimney connections, and by reference to the drawings it will be seen that atmospheric air entering the chamber 7 through the opening 6 in the bottom of the stove may be led directly into the rear of the ash-pit 4 and through the fire chamber or pot 2 and thence over the same course as that stated in connection with a current entering the draft-door 5. The door 18 is provided with a suitable arm 19, piercing the casing 1, and provided with a suitable handle 20, whereby the perforations 21 may be brought into and out of alinement with the perforatins 22 in the rear wall of the ash-pit to shut ofi. or permit the entrance of air into the ash-pit, the door being slidably mounted in the guideways 23, as clearly shown in Figs. 1 and 2 of the drawings. It will also be understood from the foregoing that the air entering the bottom of the stove may pass upwardly through the chamber 8 and enter the fire-pot 2 by way of the distributing-chamber 9 and that the aircurrent following this course may be divided, some of the air passing into the rear of the ash-pit and upwardly through the fire-pot and the other portion of the current passing upwardly into and through the air-distributing chamber 9.

It will be understood that the fuel may be supplied either through the door 24: or downwardly through the reverting chamber or dome 11 through the opening 25, closed by the cover 26. All soot or other foreign matter finding its way into the bottom of the stove may be removed by entrance through the door 27.

The peculiar construction and formation of the respective parts of my improved stove are such as to present a shoulder 28 in the rear of the stove, upon which may be placed liquids, articles, or the like for heating or warming purposes, as well understood.

Pivoted by means of a pivot-pin, bolt, or the like 29 is a damper 30, the handle 31 of which projects outwardly toward the front of the stove and arranged for swinging movement upon the rack or support 32, as clearly shown in the accompanyingdrawings. This damper is designed to regulate the admission of atmospheric air at the bottom of the stove.

I claim- 1. A stove comprising a casing, including an offset portion extending throughout its width, the casing having an opening in its bottom; a fuel-chamber and an-ash-pit; a perforated air-chamber arranged at the top of the fuel-chamber; a passage communicating with the opening in the bottom of the stove for conveying air to the perforated air-chamber, said passage being confined within the casing; aslidable door in the rear of the ash-pit, whereby air may be directed from the said passage into the bottom of the fuel-chamber, said door being confined within the casing; and means con structed and arranged to convey the products of combustion downwardly over a course in the rear of the casing and upon one side thereof, then around the interior part of the casing and finally upwardly over a course in the rear of the aforesaid downward course and throughout the width of the casing, the said means being confined within the casing.
